SAFETY RAZOR AND DETACHABLE SHARPENING DEVICE THEREFOR Filed Feb. 11, 1951 INVENTOR Lam's wonswz BY and M w ATTOkJEYS Patented 9, 1935 r 7 a s I tion of New Jersey 4 Claims. (01. 51-241 This invention relates to an improved detachable sharpening device for a razontogether with an improved construction of the razor whereby.

the sharpening device maybe readily secured in operative position with respect to the blade.

7 suitable attractive design internally threaded at A more specific object of the invention isthe provision of asharpeningdisk which in conjunction with structural features of the razor will permit of a ready substitution of the sharpening disk for theguard.

Other objects will be lowing description taken in connection withthe drawing, in which V Fig. 1 is a central transverse section the head of the razor;

' Fig. 2 is a central longitudinal section through the head of the razor;

Fig. 3' is a top view of the head of the razor showing the position of the sharpeningdisk by broken lines; 7 V I Fig. 4 is a face view of the the sharpening diskj a Fig. 5 shows the sharpening disk in operative position onthe razor; and I i Fig; 6 is a diametral section ening'disk.

The razor may include a handle ID of any operating side of one end to cooperate with a threadedstud I l on which is secured an inner clamping or razorj blade supporting plate l2 which is provided with studs l3 and M, the enlarged central portions of which pass through apertures or an elongated slot, if desired, in the razor blade l5and the outer ends of which are provided with heads I6- and I! to which the outer clamping plate It! may be secured by bayonet slot'connections, as shown. The outer clamping plate 18 isjprovided with a suitable matted or roughened'portion' to facilitate moving the clamping plate into and out of position.

Resting against the upper; end of the handle l0 and surrounding the stud H is alimitingicollar 20 which supportsthe guard supporting mem 7 V blade sharpening means rotatable about said ber 2| on which are formed the guards 22 and 23 which may be of any suitable construction, and preferably are provided at each end'with a raised portion 24 for spacing the razor blade 15 from the guard properas clearly indicated in Fig. 1.

The sharpening device'may comprise a disk 25,

the. operating side of which may beprovidedwith concentric and tangential grooves defining, in effect, raised portions, as indicated in-Fig. 4, and

or any suitable surface. Mounted on the'disk 25'is a sleeve 26 provided with a shoulder at each end, one of which normally presses. against a shoulder in a recess in the operating face of the disk, and the other of which constitutes an abut f mentfora spring 2'! bearing against the opposite side of the face ofthe-disk When it is desired to sharpen one disk 25 may then be assembled on thethreaded stud H, after which the handle, ID is threaded through on the stud and'is turned until the parts assume thepositionsshown in Fig. 5 in which the spring ZTpresses the disk 25 into operative contact with the edges of the .razor'blade. The di'skthen is rotated tosharpen the adjacent sides or faces of both edges'of the razor blade.

When it is desired to sharpen the other sides or faces of the edgesof the razor blade the upper sideofthe' y razor blade thefhandle I0 is detached, after which the spacing collar 20 and guard member 21 may be withdrawn. The sleeve ZSand the a olamping'member I8 is removed and the blade is reversed after which the clamping plate is again parts are then assembledasdescribed.

As shown in Fig. 2 the guard supporting memberfZ I may be provided with an alining and spac- 'ing stud 29 to cooperate with eitherone' of a pair of alining holes 30and 3| in the inner'cla-mpin'g' tobe. understood that the invention may be cara v .35 apparent to those skilled inthe art after this j ried out by other embodiments which may be invention is understood, and that the terms" in the claims are terms of description rather than [What I claim is:v
